SPECIFICATION forming part of Letters Patent No. 663,738, dated December 11, 1900.

Application filed October 23, 1899. Serial No. 734,427. N model.)

T0 at whom it may concern: nnlar raceway receives a second series of Be it known that I, GEORGE O. DRAPER, of balls 4, which latter travel upon the upper Hopedale, county of Worcester, and State of end of the hub ct and the adjacent part of Massachusetts, have invented an Improvethe dead-spindle. The balls 4 sustain the 55 ment in Spinning Apparatus, of which the whirl and its load vertically and in connecfollowing description, in connection with the tion with the balls 3 position it axially as it accompanying drawings, is a specification, is rotated. Upturned lugs or projections 10 like characters on the drawings representing on the top of the whirl are adapted to enter like parts. transverse slots 0 in the base 0 of the yarn 6o [0 This invention relates to apparatus for spincarrier or bobbin 0, preferably made of wood ning yarn; and it has for its object the proor other suitable non-metallic material, and duction of simple and light-running appara having at its upper and lower ends internal tus at a low cost of production. bearing portions 0 c to engage the dead-spin- In my present invention the yarn carrier dle with a running fit.

Ihave also shown in Fig. 5 that the yarncarrier D does not contact at its base with the deadspindle A, but travels on a ball-bearing formed by antifriction-balls and held in an annular recess d in the yarn-carrier, retained therein by a cap 01 on the lower end of the yarn-carrier, the exposed parts of the balls resting upon the spindle. At its upper end the yarncarrier may be provided with a contained bearing similar to that shown at 0 Fig. 1, or any other desired form of bearing may be employed.

Another form of ball-bearing for the yarncarrieris shown in Fig. 6, the yarn-carrier H having a large axial bore h, which is socketed, as ath', to receive antifriction-balls 7L2, held in place by annular bent-over keepers h which can be forced into the bore, the balls traveling upon the spindle A when the yarncarrier is rotated.

Various changes may be made in the construction and arrangement herein shown and described without departing from the spirit and scope of my invention.

The term ball or ball-bearing as herein used and hereinafter used in the claim is intended to cover all revolving devices for the purpose, whether in the shape of spheres, cylinders, or other well-known shape used for such purposes.

Having fully described my invention, what I claim, and desire to secure by Letters Patcut, is

A dead-spindle, a concentric ball-support having an annular raceway and an upturned hub, a whirl having its bore shaped to form upper and lower ball-raceways, and two series of antifriction-balls interposed between the whirl and the hub and raceway of the ballsupport, the upper series of balls traveling upon the upper end of the hub and the adjacent portion of the spindle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE o. DRAPER.
